Subagent Parallel Execution Skill
You have the subagent_spawn tool to run multiple tasks in parallel using background subagents.
When to Spawn Subagents
Spawn subagents when the user's request contains multiple independent tasks that can run concurrently. Look for patterns like:
- Explicit lists: "搜索 A、B、C" / "search for X, Y, and Z"
- Parallel intent: "同时/并行/分别/一起/分头" / "in parallel / at the same time / concurrently"
- Background intent: "后台处理" / "run in background"
- Batch operations: "帮我查一下这几个..." / "look up these things..."
- Multiple independent questions in one message
Do NOT use subagents for:
- A single task (just do it directly)
- Tasks that depend on each other's results (run sequentially instead)
How to Execute
- Decompose the user's request into independent sub-tasks.
- Call
subagent_spawn once per sub-task — do this in a single turn, calling the tool multiple times.
- Give each subagent a clear, self-contained task description including all context it needs.
- Use the
label parameter to identify each subagent (e.g., "Search: topic A").
- Confirm to the user that N subagents have been dispatched and results will arrive shortly.
Task Description Best Practices
Each subagent runs independently with no shared context. Write task descriptions that are:
- Self-contained: Include all necessary context, URLs, keywords, constraints
- Specific: "Search for the latest price of Bitcoin and summarize in 2 sentences" not just "Bitcoin"
- Action-oriented: Tell the subagent exactly what to do and what output to produce
Example
User: "帮我分别搜索一下 Rust、Go、Zig 三个语言的最新版本和主要特性"
You should call subagent_spawn 3 times:
subagent_spawn(task="Search for the latest version of Rust programming language and summarize its main features in a concise paragraph.", label="Search: Rust")
subagent_spawn(task="Search for the latest version of Go programming language and summarize its main features in a concise paragraph.", label="Search: Go")
subagent_spawn(task="Search for the latest version of Zig programming language and summarize its main features in a concise paragraph.", label="Search: Zig")
Then reply: "已派出 3 个子任务分别搜索 Rust、Go、Zig 的信息，结果会自动推送给你。"
Result Delivery
Subagent results are automatically announced back to the session that spawned them. You do NOT need to manually send results — the system handles delivery via the originating channel (Telegram or Web UI).
Important Notes
- Subagents cannot spawn other subagents (no nesting).
- Each subagent has its own session and tool access (web_search, bash, read, write, etc.).
- If a subagent fails, the error is also announced back automatically.
- Don't wait for subagent results — they arrive asynchronously. Move on or tell the user to wait.
